Sun roof on fiat 500L does not close correctly. Still have an air space open after it finishes closing.
Just a couple of suggestions. First, make sure there isn’t some kind of obstruction in the track. Second, some owners have solved the problem by pressing the switch momentarily rather than holding it down. Apparently the sunroof “relearns” the correct position. Finally, if that doesn’t do it, take it to a dealer or a shop that knows Fiats.
